BeFree 0.6L Water Filter, Fast Flow, 0.1 Micron EZ Clean Membrane for Endurance Sports, Camping and Backpacking (8019639)

As a field biologist and avid outdoorsman I have used my fair share of water filters. The Katadyn BeFree has been my favorite and is my go to for most adventures. The squeeze bag is so easy and fast to use and is very durable. The filters are a breeze to change, reasonably priced, and last a decent while. I do like the 1 L over the 0.6 L bag as it's really not much heavier and you get more filtering capacity with each use.

I drank the filtered water and use the filtered water to brush my teeth. It smells a little bit but it gets better later on.I am treveling around Peru. I had severe watery diarrhea even though I ate cooked food and drank only bottled water. I heard some people fill used water bottles with tap water and sell it. Once, the bottle was a little bit suspicious in a restaurant but I drank it. The next day, severe watery diarrhea started. This filter saved me.It can be easily squeezed and the water flow is good. Easy to use.I don't keep water in there as other reviewer recommended.

This is so much better than my Sawyer that requires hard squeezing and needing another bottle to filter into. You can walk by any stream and just fill up and drink directly from this, no need to set down your backpack or waste time. I had no issues or leaks on a 6 day hike.

This is an absolute game changer for backpacking. The flow rates out of this are incredible compared to my old Sawyer Mini. This filter does not adapt to as many water pouches and bottles as the Sawyer does, but it's bag folds up so much smaller and it's flow rate is so much faster that I have never found myself upset that I had to squirt the water into another bottle or pouch rather than being able to tether a clean container to the end like the Sawyer. The flow rate is such that it is nearly free flowing when drinking directly out of the filter cap.I used to dread the frigid hands, long stops, taking off my pack to pull out all of the components and endless squeezing of my old system to the point where I would end up dehydrated. This filter has changed the game. I typically filter a couple of liters in the morning that I carry as a backup in my pack and then keep the filter at hand and drop it in any water source I pass since it's so easy to drink right out of the filter and that way I'm not trying to filter a full days worth of water in the morning and carrying it throughout the day.

This bottle is light and convenient with a filter. Bought for a hiking trip in Spain where I may need to filter to obtain clean drinking water. But it’s not for sport activities because you can’t put electrolytes in it.

Ditch your Sawyer and Be Free!. The large opening makes filling a breeze and MUCH better than filling a sawyer squeeze pouch or a smart water bottle. I only needed a scoop on the very shallowest of water sources. I tested this over a couple week section hike on the AT. I had a Sawyer squeeze set up for gravity feed with a CNOC bladder (My old go-to) and this Katadyn BeFree that I was deciding on. Since I was starting at Amicalola, I knew I would be at Mountain Crossing in a few days, so I left the Sawyer at home and just brought the BeFree. I figured I could replace it at Neil's Gap if it sucked. It does not suck. I could gather from 99% of water sources without scooping, and filter directly into my smart water bottles from the BeFree. The flow rate is incredible. I would be done filtering 2 liters and cameling up on the 3rd before folks with Sawyers were done filtering their first liter.The flow rate is high enough to drink directly from the BeFree if that's your style. I have tried this previously with the Sawyer filters and found it to be a less than satisfactory process. The mini has too little flow and, even when used in-line with a bladder, the flow rate is terrible and will leave you sy=ucking hard on your bite valve to just get something to drink. The Squeeze is also difficult to drink directly from for a couple reasons: You have to squeeze the bottle hard to get water into your mouth and the bottle crushes, leaving low pressure in the bottle forcing you to break the seal to allow the pressure to rebalance.

I feel 100% confident drinking out of basically any water source with this filter. I’ve filtered from a Really small, muddy puddle and had no problems. It’s freedom to be able to go for runs and hikes and only have to be concerned with making sure there are streams or rivers or ponds somewhere along the route and not about carrying water. IN love.

I just took my BeFree on the Kalalau Trail in Hawaii. Two days of hiking, 25 miles over some pretty crazy terrain. Water sources were plentiful, and I saw many other hikers filling water bottles and using various filters. The best part of the BeFree? I would stop at a creek just long enough to refill the squeeze bottle, then continue on my way. Most other hikers I saw were putting in a lot of time, effort, or both using other filters. The BeFree was just so quick and easy, I can't imagine it being any better!Also, I would like to confirm that it does exactly what it is supposed to do. I drank water from streams for two days using my BeFree and felt great. I met a local on the trail who had been drinking straight from the stream....and was sick as a dog. So glad I had my BeFree!
